APPARATUS FOR ELEVATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 558,173, dated April 14, 1896.

Application filed October 4, 1895. Serial No. 564,593. (No model.)

compressed air or gas is introduced into the lower part of a partially-submerged openended tube or pipe for elevating the liquid therein above the point of submergence; and

the object of my improvement is to provide portable means for causing liquids to flow from a lower to a higher level in the process of manufacture without the use of suctionvalves, said means being more especially adapted for use in the manufacture of sulfuric or other acids which are dangerous to handle and so destructive of the apparatus as to require its frequent inspection to prevent loss by leakage. I attain the object by the means illustrated in the accompanying drawings, in which- Figure lis a side elevation of an apparatus embodying my improvement, the same being represented as suspended in a well-shaft. Fig. 2 is an enlarged detail showing partly in vertical section a fragment taken from the top part of the apparatus proper. Fig. 3 is an enlarged detail showing in side elevation a fragment taken from the bottom part. Fig. 4 is a cross-section.

The apparatus comprises a fold of pipe whose ends are provided with suitable means for readily attaching and detaching the ends of similarly-formed induction iand eduction pipes, an air-pipe communicating at one end by an air-tight connection with one member of the fold above the bottom, the other end being provided with suitable means for readily attaching and detaching the similarlyformed end of a supply-pipe coming from a suitable source of compressed air, and a hanger suitably connected with the fold and air-pipe, whereby they are united so as to be suspended in a well-shaft by the hanger while connected in use or lifted out of the Wellshaft by the hanger when detached from the induction and eduction pipe for inspection and repair.

In the drawngs,A designates the fold of pipe, whichl is made of lead, for transporting sulfuric acid, the ends abeing flanged,where by the similarly-flanged ends of the eductionpipe A and the induction-pipe A2 may be readily connected and disconnected bymeans of screw-bolts a.

B designates the air-pipe, also of lead, one end of which enters one member of the fold at b, passing through an opening in the wall of the folded pipe A and being soldered in so as to form an air-tight communication there- With.

B is the air-induction pipe shown in fragment, by which compressed air is brought from any suitable source of supply and delivered into the pipe B.

C designates the hanger,which comprises a rod of iron or other stout `material provided with an eye c for a cross-bar c, by which it may be suspended from the cover D of the Wellshaft D, and also with an eye c2, by means of which the hook of a lifting-derrick may be connected for lifting the apparatus out of the well-shaft. The hanger is connected with the fold and the air-pipe by means of an intermediate lead tube of, which is compressed upon the hanger-rod, so as to enter threads or other depressions made therein, whereby its surface is roughened or made so uneven that the tube compressed upon it will be iirmly fixed thereto, and then soldered to the fold and compressed-air pipe preferably along the entire length of the hanger-rod, which is `preferably extended along nearly the whole length of the fold.

`When the liquid is introduced into the fold through the induction-pipe A2, it will rise in the fold and in the air-pipe to the level of the induction-pipe or the source of supply. In such condition a sufficient force of compressed air is turned on to force the liquid outof the air-pipe into the fold and cause it to rise in the eduction-pipe A and flow out of the open end thereof at the top into a suitable receptacle B2 above the level of the supply. After the column of liquid in the member ofthe fold to which the air-pipe is attached has been forced out the air-pressure may be reduced and will then form air-bubbles in that side of the fold, causing the liquid to rise in and be discharged from the open end of the eduction-pipe above the level of the supply.

What I claim isan eduetion extension to its opposite ends,

l. An apparatus for elevating liquids eoman air-pipe having` one end entered into one prising a fold of open-ended pipe, and an airmember of the fold above its bottom and the pipe having one end connected With one memother end provided With means for attaching i 5 5 ber of the fold above the bottom, said fold and detaehing,` an induction extension, and a and an air-pipe being united by a hanger for hanger provided with eyes and Connected suspending,` them in and lifting them out of a with the fold and airepipe as specified.
